A tsunami is a long wave. The length of the wave is much longer than its depth. A typical tsunami wave in deep water is several tens to hundreds of kilometers long. Hence even if such a wave propagated over a 4000- m-deep abyssal plain, its evolution would be strongly affected by the bottom bathymetry. This is not the case for storm-generated waves, which are typically less than 500 m long; waves whose length is less than twice their depth are not affected by the presence of the ocean bottom.
